As the cars are almost identical, I thought I'd post here as well. Another uncommanded acceleration from the 2009 Aspen. This time the wife rear ended someone. Minor damage and no injuries thank God. Same scenario each time. Brakes applied and almost to a complete stop when it suddenly goes full throttle. Then after a few seconds it returns to normal. Did it to me once, did it to the wife twice. Anyone else have this experience? Any idea what could cause it. The first time it happened to the wife it was blown off as she hit the throttle and brake at the same time. Then it happened to me.
